SPECIFICATION forming part of Letters Patent na'ro z lsa, dated August 19,1902. Application filed February 12, 1902. Serial No. 93.770. (No model.)

, To all whom it may concern:

Be it known that I, J AMEs MARSHALL, a citizen of the United States,residin g at Fall River, in the county of Bristol and State of Massachue setts,have invented a new and useful Improve ment in Machines for Circulating and Separating Waste Fibrous Materials, of which the following is a specification.

Heretofore it has been the customto feed the raw fibrous materials to a purifying-machine either by hand-labor distributing the raw materials upon a feeding-apron or by occasionally filling a feeding apparatus whichacts automatically as a distributor of the materials upon the apron; but in all cases the wastes or droppings from the purifying process fall upon a bottom apron which'oontinuously returns them to the front of the machine, where they are gathered by hand-labor and returned to the feeding-apron for reaction by the machine, or they are returned automatically by a continuation of the bottom apron to the feeding device. In the first case the operator has an opportunity to distinguish and separate what portions of the wastes are worthy of reaction. In the latter case though some labor is saved everything is returned to the purifying-machine for reaction, and the process is repeated over and over at a waste of time and power and to the deterioration of the product. V

The object of my invention is tosupplylau auxiliary device for automaticallyreceiving, separating, and returning only the useful portion of the wastes to the originalmachine by a continuous circulating system so arranged rials. a

In the accompanying drawings like figures and preventing reaction on worthless mates of reference relate to like parts.

Figure 1 is a front view-of my device. I Fig. 2 is aside View. Fig. 3 is a plan view. Fig. 4: is a front view, the separator being shown in section through the line a; of the plan. A

As shown in'the' drawings, 1 is a feedingtable as ordinarily arranged in front of any fiber-purifying machine. 2 is the feedingapron, passing over roller 3 and entering the machine 4. The lower return-apron is shown 'at5, passing over roller 6 and delivering the I waste droppings to the front of the machine. All the-above is as usually arranged in this class of purifying-machines. At this point I begin to arrange my automatic improvement by supplying a pan 7, arranged upon the floor to receive the waste droppings from the return-apron 5. I connect this pan by means of the pipe 8 with an exhaust-fan 9,

which removes its contents and delivers them through a pipe 10 into a separating-chamber 11. for a suitable height and then preferably tapers pyramidally to a top outlet 12 and de livery-pipe 13. The entrance-pipe 10 is continued perpendicularly within the chamber to a suitable height dependent upon the force of the blastiused and the nature of the materials to be separated. The oflice of this pipe is to discharge the waste materials upward and keep them in rebounding circulation by means of "the supporting-wind until the-heavier impure materials settle outand drop to the bottom of the separator, while the better ingredients, which are always the lightest pass on through the delivery-pipe 13 to a funnel-shaped cage 14:, arranged over the feeding-apron. chiefly of wire -cloth, so as to permit. the quick escape of the accompanying air, while the recovered materials drop upon the feed-' suckedby the fan9 through pipe 8 and delivered through pipe 10 into the separating- Y I chamber 11-; There the impure parts settle,

and the purified'pa'rt passes on through pipe 13 and cage 1 1 back to the feeding-apron 1 of the original machine. By this means I keep up automaticallya continuous circulat- This cage is constructed ing system of the separated waste products.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- 1. In a machine for purifying fibrous ma terials, the combination therewith of an auxiliary system continuously circulating the waste or droppings therefrom, consisting of a receiving-pan into which said droppings fall, an exhaust-fan emptying said pan, 2. separating-chamber into which said pan delivers its exhaust, and a pipe leading the purified products from said separating-chamber back to the original machine, substantially as described and shown.

2. In an auxiliary machine for separating the wastes made from purifying fibrous materials the combination with the outlet through which the waste products of the original machine are discharged, of a receptacle into which they fall, an exhaust-fan connected to said receptacle removing and conveying said wastes forward, a separating-chamberadjoining, into which they are discharged and a return-passage from said chamber to the original machine substantially as described and shown.

3. In a machine for separating the wastes made by purifying fibrous materials, the combination of an auxiliary separator consisting of a chamber into which the Wastes are discharged, an inlet-pipe rising through said 'nected to a passage terminating in a wire cage erected over the feed-inlet of the original machine, through which passage, the recovered Wastes are returned by means of the aircurrent generated by the fan, to the original machine, substantially as described and shown.
